Jewelry Box Brand "sentoujours." to Hold a Gallery Exhibition with Jeweler Ayako Sakurai at GINZA SIX! A Special 2-Day Limited Exhibition on May 15 (Fri) & 16 (Sat), 2026

STJ Creations Inc. (Head office: Ebisu, Shibuya-ku, Tokyo), which operates the jewelry box brand "sentoujours.", will hold its first collaborative event with jeweler Ayako Sakurai for two days on Friday, May 15, and Saturday, May 16, 2026, at GINZA ATRIUM, Tsutaya Books, GINZA SIX. This event, themed "Two Days That Will Change How You See Jewelry," will be held as a gallery for "AYAKO SAKURAI," offering an exhibition experience where visitors can feel the beauty of jewelry and the reasons for being drawn to it through "seeing," rather than purchasing. "AYAKO SAKURAI" believes that jewelry is not only "something to wear" but also "art to be adorned." "sentoujours." serves as a canvas or stage that makes such jewelry even more attractive. We hope that this event will be an opportunity for both jewelry enthusiasts and those who previously had little interest, to be deeply moved by works or photographs they happen to see. Please feel free to drop by and immerse yourself in the beauty of jewelry and tweed. ◆ Event Outline Period: Friday, May 15, 2026, Saturday, May 16, 2026 Time: 10:30 AM - 8:30 PM (Closes at 7:30 PM only on the final day) Location: GINZA ATRIUM, Tsutaya Books, 6F GINZA SIX The following "sentoujours." products can be purchased at the venue. ・Jewelry Box "Eternelle" ・Jewelry Box "Eternelle mini" ・Jewelry Box "Chance" ・Jewelry Box "Aurélie" ・Micro Bag "Durée" Additionally, customers who purchase products will receive one "Jewelry Wrap Set (Pink/Blue)" per person. *While "AYAKO SAKURAI" jewelry is generally not available for purchase, only the new "KAME" earrings can be purchased and taken home. Please speak to staff on the day if you are interested in any jewelry. ◆ About "AYAKO SAKURAI" With procurement routes and aesthetic discernment inherited from her mother, Ayako Sakurai began disseminating information about jewelry on social media in 2019. She was the first to introduce the new option that "there are various ways to buy gemstones other than high-end brands" on Instagram, and is now considered the originator of the trend where more people call themselves "Instagram jewelers." Her theme is "Towards an era of freedom in choosing gemstones." She continues to provide a personalized selection experience that emphasizes "who you buy from," through a trinity of in-person sales (Sakurai-style "consultative selling"), Instagram sales (started in 2022), and a members-only e-commerce site "A JEWELRY BOX." The operation is run by a lean, elite team including her husband, who is also her business partner, and a close friend since high school. She has over 25,000 Instagram followers. Through daily broadcasts, she provides tips to enhance one's perspective on stone selection and outfit resolution. Serving as her own spokesperson, she published her first book, "You Don't Need Brand Fees for Gemstones," in February 2023. Her limited-time shops, which create a different world view each time, cover a range from high-priced to affordable items. At Shibuya Scramble Square, she recorded the highest sales in the history of pop-up stores there, reaching 170 million JPY (over 3 days). By arranging a flow that allows customers to experience "concierge-style selling," she provides a high level of satisfaction. By accompanying customers through size, color, and compatibility with existing jewelry, she gently fosters the ability to "choose a piece of jewelry that will be a lifelong companion, in your own unique way." ◆ About "sentoujours." "sentoujours." is a word created by combining the Japanese "sensu" (folding fan), the French "toujours" (always, eternity), and the English "sense." The folding fan, with its expanding shape, is a traditional Japanese good luck charm symbolizing future possibilities and good fortune. By overlaying the meaning of "sense" onto this, it expresses the power to believe in one's own intuition and forge one's path. Inspirations and choices brought by intuition lead to infinite expansion and good fortune in the future. We, sentoujours., wish to create a space where everyone can shine in their own unique way, by their side. Hoping that intuition and instinct will guide the future and create eternal brilliance. ・Official Online Site: https://sentoujours.com/ ・Official Instagram: https://www.instagram.com/sentoujours.off
